Method for Optimizing the Production of a Rotor Spinning Machine
First Claim
1. A method for optimizing production of a rotor spinning machine having a plurality of identical spinning units, with each spinning unit having a spinning rotor, and wherein during operation of the rotor spinning machine, the spinning rotors are driven by a rotor drive, rotate at a rotor speed, and provide a yarn at a delivery speed, the method comprising:
- specifying a permissible range with a minimum delivery speed and a maximum delivery speed for the delivery speed of the spinning units;
starting operation of the spinning units with a starting delivery speed within the permissible range;
continuously monitoring and calculating current energy consumption of the spinning units or the rotor spinning machine;
regulating current delivery speed as a function of the current energy consumption in such a manner that a minimum energy consumption is achieved, comprising decreasing the delivery speed from the starting delivery speed until the minimum energy consumption is reached and only increasing the delivery speed when the minimum delivery speed has been reached or an increase in energy consumption results from operation at the decreased delivery speed.

Abstract
A method optimizes production of a rotor spinning machine having a plurality of identical spinning units, with each spinning unit having a spinning rotor driven by a rotor drive at a rotor speed to produce yarn at a delivery speed. A permissible range with a minimum delivery speed and a maximum delivery speed for the delivery speed of the spinning units is specified. Operation of the spinning units is started with a starting delivery speed within the permissible range. Current production capacity of the spinning units or the rotor spinning machine is continuously calculated. Current delivery speed of the yarn is regulated as a function of the current production capacity in such a manner that a maximum production capacity is achieved. A rotor spinning machine in accordance with method is also provided.

11. A rotor spinning machine, comprising:
-
a plurality of spinning units, each spinning unit comprising; a spinning rotor with a rotor drive wherein the spinning rotor is driven with a variable rotor speed during operation of the rotor spinning machine; a draw-off device by which a produced yarn is removed from the spinning unit at a delivery speed; wherein a current energy consumption of the spinning units or the rotor spinning machine is continuously calculated; a control unit configured to regulate the delivery speed within a permissible range having a minimum delivery speed and a maximum delivery speed based on the current energy consumption in a manner such that a minimum energy consumption is achieved; and wherein the control unit is configured to regulate current delivery speed as a function of the current energy consumption in such a manner that a minimum energy consumption is achieved by decreasing the delivery speed from the starting delivery speed until the minimum energy consumption is reached and only increasing the delivery speed when the minimum delivery speed has been reached or an increase in energy consumption results from operation at the decreased delivery speed. - View Dependent Claims (12, 13, 14, 15, 16)
